Can I use Gemini for free?

Hello there! I'm curious about Gemini, a popular cryptocurrency exchange platform. My question is, can I use Gemini for free, or do they charge any fees for using their services? If there are fees, could you please elaborate on what those fees are and how they might impact my trading experience? Also, are there any other costs associated with using Gemini that I should be aware of? I appreciate your help in clarifying this matter. Thank you!
